As of the beginning of this year, the most advanced LED package costs fluctuated around $10/1000lm. But because blue light and phosphors are combined for optimum efficiency, this number only applies to the cool white light that both designers and consumers dislike. As the LED market continues to grow and expand, the annual output value has nearly doubled last year, and semiconductor lighting bulbs are increasingly appearing on the shelves of household items.
It seems to be telling people that the era of solid-state lighting has come. In the past few years, the energy efficiency of white LED chips, packages and lamps has been significantly improved, but general lighting is still in a very early stage of development.
Most of the evaluations suggest that LEDs currently have a penetration rate of less than 5 in general lighting. Although designers are keen to explore the various possibilities of LED lighting technology applications, consumers will be happy to accept lighting solutions that can save them money, but LEDs still have many problems to solve in the lighting market. The current status of LED lighting applications is a question of when, not if.
For a large-scale TV or car, choose a product that meets the LED requirements of the application. Therefore, its LED products will be a single type of product, which is convenient for mass production. In other words, there is no nuance. Millions of TVs or cars use almost the same equipment. However, in the field of general lighting, the demand for different types of applications, whether it is work lights, residential, office or street lights, will be very different, making LED light sources not a universal product in this field.
For outdoor lighting, such as street lights, LED lighting has been widely activated. Obviously, the general lighting market is actually made up of many different markets, and the demand points are different. Of course, the cost requirements are consistent. LED lighting has more potential than traditional lighting. Another significant advantage of LED lighting is that the LED light does not emit ultraviolet light. Ultraviolet light from traditional halogen or fluorescent lamps can cause discoloration of textiles over time. If the clothes are displayed under strong light, they will degrade rapidly. Similarly, illuminating food with LEDs will result in a longer shelf life, thus avoiding heat from traditional lighting.
Since the fourth quarter of last year, the price of LED packages has dropped by 20-25. StrategiesUnlimited also predicted that the average price of outdoor lighting will continue to fall in 2011, and this trend is likely to continue and accelerate in 2012.
Although the compound annual growth rate (CAGR) of LED lamp shipments from last year to 2015 is expected to be 26, due to price cuts, the compound annual growth rate of revenue is expected to be only 11 and revenue is expected to reach 2015. $ 544 billion. According to the market analysis and forecast report of LEDs for outdoor and large space lighting released by market research company StrategiesUnlimited, the United States has taken a leading position in the field of LED outdoor lighting. The report believes that although China has installed a lot of outdoor lighting fixtures, due to quality problems, the scale of China's outdoor LED lighting market has shrunk in 2011. In North America, with the joint efforts of the US Department of Energy, the US Urban Solid-State Lighting Street Light Association, and the American Lighting Design Association, people's awareness of quality continues to increase, and the transition from traditional lighting to LED technology is promoted.
